Exclamation Backup Cam flickering.

I installed my new Backup cam today , but when I press the gas the picture flickers. This also happens when I turn the headlights on and off. I accessed a ground (brown) and a 12v(grey/yellow stripe) from the Tail light harnest. I used T-taps to tap in to these wires video cable is not pinched and all connections behind the radio are good.

What do you think is going wrong?

I used the accessary outlet, either the front or the back I forgot. the camera picture is solid, as clean as it could be, never had any issue over a year now.

I have the same problem before. Solved by order 12v plug from ebay and used the accessories plug in the gloves box instead connect the wire. Good luck
